The answer will be a(8b + 7c)
Answer:
720
Step-by-step explanation:
If order mattered, we would say select the first number (10 choices), then the second (9 choices) then the third (8 choices). So there would be 10 x 9 x 8 = 720 possible choices.
It should be just 12b, since they all have the same exponent, they can all be combined.
You have to divide each side by -16.
Answer Is A. First because as you can see the letters are switched.
